【推荐1】A Good Night’s Sleep
Sleep plays a vital role in good health and well-being throughout your life．While you’re sleeping, your brain is forming new pathways to help you learn and remember information. Although we all know the importance of getting a good night's sleep, not all of us know the best way of getting it. A sleep expert, Phil Atherton, gave some top tips for getting the most out of the night, which will leave you ready for action in the morning.
According to Phil Atherton, not eating a large meal before bedtime is important for getting a good night’s sleep. The time difference between eating and sleeping should be at least three hours. So you'd better avoid eating any food three hours before bed, as it will lower your blood sugar during sleep and help minimize damage from too much sugar floating around.
It’s also important to find ways to prepare your body for sleep. You can follow a routine like trying not to expose yourself to too much artificial light within 1 hour before bed, as your brain uses light to help set internal “body clock”. Although it might seem unnatural to schedule your sleep, the purpose is to send a signal to your body and mind that it's time to sleep.
Another way to prepare your body for sleep is to get into a relaxed state by taking a bath or listening to soft music. Both of them will help to take the mind off the daytime pressures.
Having a suitable bed, especially a suitable mattress (床垫), is necessary for a good night's sleep. Sleep is a personalized activity, and we all adopt different sleeping positions. Finding the mattress that suits you will reduce back pains that can result from a poor sleeping position. The bed should be four to six inches longer than its tallest user, allowing for space to move around.
The recent research is pretty clear that a good night’s sleep in a major component of good health. Since the start of the 21st century, studies have linked a lack of sleep to many diseases, such as diabetes and obesity. Taking action now will lead to long-term benefits for you and those around you.

【推荐2】How to Keep a Positive Attitude Around Negative People

You are a basically happy person and try to make an effort to stay positive. But the people you work with are so negative. How to keep your positive attitude when surrounded by negative people?     1    

First attempt to understand what you are really up against. Observe what is actually happening. What are the words, the actions, the tone of voice, the facial expressions?

    2     Are you sure? While negative words and actions are always unpleasant to be around, it is helpful to distinguish among those cases in which someone has simply fallen into the bad habit of negative talk, times when they have brought a past upset into the present? and the most difficult moments when they are actively hostile to the current situation.

    3     Even when negative talk is directed toward you, don’t take it personally. Negativity is basically selfishness, and their selfishness is about them, not about you. But this is very difficult to put into practice. When you are the target of the other person’s complaints, and especially their sarcasm, it is very hard not to take it personally. Try, however, to remain objective, and don’t take it personally.

    4    No person or situation is 100% negative. Make a list of everything that is positive about the person or situation. Keep writing until you have compiled a meaningful list. Then give thanks for all that is positive.

Consider how you can cheer up the negative person.     5    Even give them a note of appreciation or a gold star? Inquire about their family? Be supportive of their troubles without either agreeing or offering suggestions? However, if your attempts to befriend someone create more hostility, stop. There is no point in doing anything to annoy them further.

A．Think positively.

B．Don’t take it personally.

C．Have gratitude for what is positive.

D．Can you praise co-worker on a task well done?

E．Try the following tips, you will always stay positive.

F．What emotions do you sense behind the words and actions?

G．It is important to be aware of the harmful effects of being negative.

【推荐3】Exoplanets: The Hunt Is On

Today scientists believe that planets could outnumber the stars. For centuries, scientists and natural philosophers have indicated that stars in the night sky have planetary systems similar to our own solar system.    1    However, we have developed the technology to prove their existence only in the last few decades.

In 2015 NASA’s Kepler space telescope found its first Earth-sized planet in a “habitable” zone. This is the distance from a star where surface temperatures of a planet wouldn’t be too hot or too cold for liquid water. So far, only a small part of our galaxy, the Milky Way, has been explored.    2    

Because exoplanets are so far away and very close to stars, it is very difficult to see them directly.    3     For example, as a planet circles a star, it pulls on it and causes it to shake. As the star moves unsteadily, it changes the wavelength of the light we see. Measuring these slight changes is another method of discovering planets.    4     When an exoplanet moves between its star and us, it causes a small drop in the star’s brightness. By measuring this drop, NASA’S Kepler space telescope has discovered many exoplanets.

    5     As time progresses and technology improves, who knows what else we may find!

A．It is one of the most productive methods.

B．Therefore, scientists use indirect methods.

C．These are just two examples of the methods scientists use.

D．Even so, scientists have confirmed more than 3,500 exoplanets.

E．Astronomers have received signals indicating the presence of a planet.

F．Direct observation of the exoplanets is becoming increasingly possible.

G．The existence of extrasolar planets, or exoplanets, has long been discussed.
